A major dilemma faced in the nuclear industry is repair of stainless steel reactor components that have been exposed to neutron irradiation. When conventional fusion welding is used for repair, intergranular cracks develop in the heat-affected zone (

International audience; In the context of the simulation of industrial hot forming processes, the resultant time-dependent thermo-mechanical multi-field problem (v→,p,σ,ε) can be sped up by 10-50 times using the steady-state methods while compare

International audience; The problem of multi-objective optimization (MOP) is approached from the theoretical background of the Game Theory, which consists in finding a compromise between two rational players of a bargaining problem. In particular, th
